DISTILLINGAPPARATUS.

SPECIFICATION forming part of Letters Patent No. 692,788, dated February 4, 1902.

Application led May 8, 1900. Renewedvllllay 11,1901. Serial No. 59,874. (No model.)

cago, in the county of Cook and State of Illinois, have invented certain Ynew and useful Improvements in Distilling Apparatus; and

I do herebydeclare that the following is a full; clear, and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in distilling apparatus,and is designed more particularly to produce distilled water, the ooject being to improve the construction of apparatus of this character and to simplify the operation thereof.

The invention consists in the mattershere-A inafter set forth, and more particularly pointed out in the appended claims. f

In the drawings, Figure l is a side elevation of parts of a distilling apparatus made in accordance with my invention. Fig. 2 is a view, partly in central vertical section and partly in elevation, of the same in a plane at right angles to the View of Fig. 1. Fig. 3 is a vertical section of a modified form ot' the invention.

As shown in said drawings, A designates an upright jacket constituting part of a condensing-chamber, which in the form herein shown is cylindric, and B designates a boiler located centrally over said jacket and in communication with therupper end Vthereof and provided with a removable cover. Within said jacket are located a plurality of vertical condensing-pipes C, arranged symmetrically therein and attached at their opposite ends to upper and lower heads a d of said jacket. The condenser pipes open at their upper ends into an annular centrally-disposed chamber D, which is in open communication with the boiler B, and at their lower ends said pipes open into a cup E, arranged below the Water-jacket and into which the distilled water from said pipes is discharged. Suitable stuffing-boxes surround the upper ends of t-he condensing-tubes and prevent the water of condensation in the chamber D from passing into the water-jacket. The lower ends of said tubes are connected withrdrip-pipes a4, which depend from the lower wall of the waterjacket. Said cup is provided with a centrally-,located outlet-pipe E.

The arrangement of thecondensing-tubes enables the same to be removed for the purpose of cleaning` or renewing of the same upon the removal of the cover' from the boiler Bor enables the tubes to be cleaned by the 'insertion thereinto of a suitable implement when said cover is so removed.

The communication between the chamber B at the entrance of the condensing-tubes and the boiler in the instance shown consists of a short upright pipe F, whichjs opened at both ends and extends at its upper end into the steam-space of said boiler and near the top thereof to permit the entrance of steamv thereinto, and through which pipe F the steam is directed into the chamber D and condenser-tubes'. Said pipe F, as herein shown, rests on the bottom of the boiler B over a centrally-located opening in the bottom. wall b thereof. This bottom wall b constitutes the upper wall of the chamber D. The tubes C may themselves extend into the boiler, if desired. VA valved inlet-pipe A leads into the lower end of the jacket and admits water from any suitable source of supply.

A2 designates a cooling-water-outlet pipe leading from the upper end of the jacket.

Gdesignatesa steam-coillocated within the boiler, which in this instance constitutes the meansfor heating the water within the boiler. Said coilG is connected at one end with a steam-inlet pipe G', leading from any suitable source supplying steam, and is connected at its other end with a valved outlet-pipe G2, which in this instance discharges into a steamtrap H, of any preferred construction, in which the steam is condensed and the water of condensation led therefrom in the usual manner.

The pipes A' A2 will `usually embracea part of a pressure water-supply system of the building in which the device is locatedthe water being delivered to the jacket under-thepressure of such system.

The jacket, condensing-tubes, and boiler are supported on a frame consisting, as herein sho-wn, of four upright columns II, connected by transverse and oblique braces I I2, which are connected. together in a manner to form.

loo I a rigid frame. The boiler B rests directly on the upper end of said columns and is secured thereto in any suitable manner and to the jacket to provide a steam-tight joint, and the jacket A is supported from said column by means of radially-extending supportingarms 13.

The water in its natural state is l'ed to the boiler by means of a pipe J, which enters the bottom of the same. Said pipe is connected at its otherend with a feed-tank K and is provided between its ends with a suitable valve j. The feed-tank K is connected with a suitable source for supplying water and is located at the level of the boiler B, desirably closely adjacent thereto. Said tank is provided with controlling-valve mechanism, Which is constructed to automatically control the supply of the undistilled water to the boiler B, and the location of the tank and the construction of said controlling mechanism is such that the water in the feed-tank and in the boiler is maintained at the same level, so that the supply of water to the boiler is maintained approximately uniform. The undistilled water will usually be fed to the feed-tank K through a pipe L, connected with the pipe A2, leading from the upper end of the waterjaeket, so that the water to be distilled may first serve the purpose of cooling the condensing-tubes. Said pipe L discharges at its upper end into another pipe M, which enters the bottom of the feed-tank K, and the opening between said pipe M and feed-tank is adapted to be closed by means of a valve O, which is controlled by a float in the tank. In this instance said valve O is provided with a stem o, extending upwardlyfrom the bottom of the tank, and to the upper end of said stem is pivotally connected a lever P, carrying at one end a oat P and piroted between its ends on a post P2, which rises from the bottom of the tank. Said pipe M is provided with a hand-valve m, by which the supply of water to the feed-tank may be controlled. With this construction the water is fed to the device through the pipe Al under the pressure of the system of which the pipes A A2 constitute a part, and the controlling mechanism between the pipe A2 and the boiler embracing the float-valve mechanism or the regulating-valve between the discharge-pipe and boiler enables such quantity of water to be drawn from the system as required by the distilling apparatus, the volume of Water passing through the pipe beyond that required for distillation purposes remaining in the system and not wasted, as in devices of this character heretofore employed. The inletpipe M is shown as connected also with a discharge-pipe N, leading from a reservoir or tank N', in which the impurities in the undistilled Water may be precipitated before the water is discharged into the feed-tank K. Said pipe N is provided with a controllingvalve N2. Nhen water is supplied from the tank N to the tank K, the Valve m is closed,

so that no wat-er enters said tank K from the pipe A2. The tank N may receive water from any suitable source, eitherfrom the pressure system or otherwise.

Q designates a Wash-out pipe which leads from the bottom of the boiler and through which the wash-out water from said boiler may be discharged. Said wash-out pipe is provided with a valve q, by which it is normally closed.

R designates an overflow-pipe which projects through the bottom of the tank K and to within a short distance of the top thereof and by means of which the quantity of water Within the tank may be limited in the usual way. S designates a drain-pipe leading from the bottom ot' said tank and connected at its lower end with the overflow-pipe R. Said overflow-pipe is connected at its end remote from the tank K to the wash-out pipe, and through which Wash-out pipe the overflowwater and the drain from the tankis discharged. Said drain-pipe is provided with a valve s, which is kept normally closed.

In the operation of the apparatus cool water is supplied to the jacket A through the pipe A', the supply of which is regulated by means of a valve a2 in said pipe, and is led off from said jacket through the dischargepipe A2. The supply of water to said jacket is maintained sufficiently rapid to keep the condenser-tube at a temperature low enough to secure the condensation of all the steam entering the same. Water in its natural state is fed to the boiler through the supply-pipe J and the float-valve mechanism described. Steam is admitted to the steam-coil G through the pipe G and discharged therefrom through the pipe G2 to the steam-trap H. lVhen steam is admitted to said coil, the water inthe boiler B will be heated and steam formed in said boiler. In the absence of any other outlet the steam arising from the Water in the boiler B will be forced byits own pressure through the upright tube F downwardly into the chamber D and condensing-tubes C. Vhen the steam comes in contact with the Walls of said tubes, which latter are maintained at a suitably-low temperature by the Water contained within the jacket A, said steam will be rapidly coudensed and will escape down the cold walls of said tubes until it escapes into the cup E and therefrom through the dischargepipe E into a suitable vessel placed thereunder. Owing to the natural tendency of the steam to rise, it will only move down into thc condensing-tubes by reason of the pressure within the boiler, so that condensation will take place to a great extent in the upper ends of the tubes, and therefore when the parts are properly proportioned there will be no liability of the steam being driven out uncondensed into the distilled-water cup E.'

As the water is dissipated in the boiler B by its generation into steam the supply of the boiler will be automatically replaced through the pipe J from the tank K, the float in the IIO A' the end walls of the water-jacket.

tank regulating the same.

not liable to easily get out or order.

By reason of the open communication between said boiler and tank (the valve J being openduring the op-V eration of the apparatus) the water in the boiler and tank will normally be maintained at auniform level, and when the water in said tank and boiler is in balance the valve O will be closedby reason ot' the elevation of the ioatP. lowered in the tank, the float P will drop and open the valve 0 to permit a furtherisupply to enter the pipe L, thus automaticallymaintaining a constant supply of the undistilled water to the tank K and therethrough to the boiler B. In case the valve O should not act quickly or should be ineffective in its operation for any reason the supply of water in the tank t'o a greater level than desired in the jacket, a boiler supported on said jacket,.a.

boiler will be reduced Vby reason of the presi ence of the overflow-pipe R, which vprevents the water in said tank K rising beyond the level of the upper end of the pipe. In this manner I am able to maintain the operation of the apparatus entirely automatic so long as the same is operating under ordinary and usual conditions.

My apparatus is simple, cheap, durable, and

yIn Fig. 3 I have shown a modified construction wherein the plurality of 4condensingtubes shown in Fig. 2 is replaced by a single spirally-arranged condensing-tube T, which passes vat its upper end throughthe upper end wall @Slot the water-jacket, and at its lower. end through the lower wall dfi thereof. Stufiirngfboxes surround the endsof said tube at the places where itlpasses through' The upper end of said tube passes centrally through the upper wall of the'water-jacket, and the upper surface of said upper w'all is inclined towardl its center, so as to direct the water falling on said wall to the tube. Theother part of the. apparatus may be like similar partsof thepreviously-described iiguresiand are herein designated by like reference-let-` ters. The provision of the single spirallyarranged tube` may be made as effective as the prior construction and` avoids the necessity ofv a large number of stuffing-,bones between the tube and the ends of the waterjacket.
